Cardiac Glycosides from the Roots of Streblus asper
26 February 2007 (online)
A new cardiac glycoside “vijaloside” in addition to well known cardenolide, asperosid (digitoxigenin-2′,3′-di-O-methylglucopyranoside) have been isolated and identified from the roots of Streblus asper. Repeated chromatgraphic manipulations and spectral analysis (IR, 1H-NMR, 13C-NMR and Mass), suggested the structure of vijaloside as periplogenein-3-O-β-D-glucopyranosyl (1 → 5)-O-β-D-xylofuranoside.
